This cop checks for every useless assignment to local variable in every
scope.
The basic idea for this cop was from the warning of ruby -cw:
assigned but unused variable - fooCurrently this cop has advanced logic that detects unreferenced reassignments and properly handles varied cases such as branch, loop, rescue, ensure, etc.
Example:
# bad
def some_method
some_var = 1
do_something
endExample:
# good
def some_method
some_var = 1
do_something(some_var)
end
